This patch adds a `psci_validate_state_coordination` function that is called by `psci_cpu_suspend_start` in OS-initiated mode. This function validates the request per sections 4.2.3.2, 5.4.5, and 6.3 of the PSCI spec (DEN0022D.b): - The requested power states are consistent with the system's state - The calling core is the last running core at the requested power level This function differs from `psci_do_state_coordination` in that: - The `psci_req_local_pwr_states` map is not modified if the request were to be denied - The `state_info` argument is never modified since it contains the power states requested by the calling OS This is conditionally compiled into the build depending on the value of the `PSCI_OS_INIT_MODE` build option.
